What is 350 percent of 2.1 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 2.1 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 2.1 is 100%, so we can write it down as 2.1=100%.
4. We know, that x is 350% of the output value, so we can write it down as x=350%.
5. Now we have two simple equations:
1) 2.1=100%
2) x=350%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
2.1/x=100%/350%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 350% of 2.1

2.1/x=100/350
(2.1/x)*x=(100/350)*x       - we multiply both sides of the equation by x
2.1=0.28571428571429*x       - we divide both sides of the equation by (0.28571428571429) to get x
2.1/0.28571428571429=x
7.35=x
x=7.35

now we have:
350% of 2.1=7.35
